Review on Prime Products 08 5015 Universal Utility: Your All-in-One Solution for Efficiency and Convenience by Jeremy Bradford

Bought a couple of these for use on a van - they look great but are very poor quality. The inner positive contact rotates and touches the negative ring (see photo), shorting the socket and blowing the fuse. Also, the small nut on the back of the electrical connector does not turn far enough to secure the wire without damaging the material. Unfortunately I didn't find that in my 30 day window so now I'm stuck on six of these and can't get them back. I wish Revain had a better policy on poorly made hardware.
